Voices of the Rocks: A Scientist Looks at Catastrophes and Ancient Civilizations

Asked to investigate the Sphinx at Giza, Schoch was troubled to find evidence of a much greater age than the 4,500 years suggested by Egyptologists. This led him to examine the possibility of a lost civilization dating back to at least 10,000 B.C. Looking at linguistic, geological, and archaeological evidence from around the world, he proposes an outline of prehistory that differs markedly from our received wisdom--after all, if the Lascaux cave paintings really are star maps, then we've got a lot of catching up to do. Schoch's willingness to dismiss implausible evidence and to use Occam's razor to cut away unnecessary complications is admirable and refreshing in a field in which credulity pays and skepticism is viewed with deep suspicion. Ending on a note of warning, Voices of the Rocks reminds us that by weakening the planet, we have made ourselves much more vulnerable to the next global cataclysm, which may come at any time. --Rob Lightner
